Hello.I manually compiled dolphin-emu 5 on my test system, and i can start it form a terminal by just typing "dolphin-emu".I can also start games, so it's installed fine.Problem is Wahcade can't seem to find it.In Application i tried dolphin-emu or dolphin-emu-nogui, but wahcade says it's not installed.This is what i get if i do "locate dolphin-emu" in a terminal:

which dolphin-emu did the trick.It was in /usr/local/bin. I could have guessed.Now for the ini: if i use : /usr/local/bin/dolphin-emu and: -b -e "[rompath]/[name].[romext]" the game starts, but the dolphin-emu frontend starts in front of the game.If i use: /usr/local/bin/dolphin-emu-nogui and: -e "[rompath]/[name].[romext]" (without the -b), the game starts allright, without the frontend, but the "esc" doesn exit the game, but only pauses it.So i still have to find a way to exit the game and get back to wahcade.I also found out there is a "ppa" for dolphin-emu 5, so the whole compiling thing wasn't necessary.

I also found out how keep the dolphin-emu frontend to the back.In the graphics setting i had to choose: keep window on top.So the wahcade ini is now: application: /usr/local/bin/dolphin-emuCommand line: -b -e "[rompath]/[name].[romext]"Now it works fine.
